What is the average acceleration of a subway train that speeds up from 9.6 m/s to 12 m/s in 0.8 s on a straight section of track? Show your work below.

What is the average acceleration of a subway train that speeds up from 9.6 m/s to 12 m/s in 0.8 s on a straight section of track? Show your work below.

Average acceleration = change in velocity/ change in time
=12-9.6/.8=2.4/.8=3m/s²
